Clarification of RCD (R-link Channel Descriptor) and RS_Config-CMD
(RS Configuration Command) messages
Introduction
This contribution is exactly the same as contribution C802.16j-07/545r1 but restoring the CID_ALLOC-REQ
message for embedded path management.
Original CID_ALLOC-REQ message is used for both CID pre-allocation and embedded path management, and
this make confusion of the usage of CID_ALLOC-REQ as comment #340. As a result, we use
RS_Config_CMD message as proposed in contribution C802.16j-07/545r1 for CID pre-allocation method and
use original CID_ALLOC-REQ message for embedded path management. More clarification of CID_ALLOCREQ shall be described in the contribution C80216j-07_558r2.

Figure 1 Evolution of RS configuration messages
Recommendation
Separate RS configuration parameters into two categories:
1.
RCD (R-link Channel Descriptor) message: A MR-BS either broadcasts RCD message to all RSs or
unicasts the message to a RS. The message will contain R-link parameters as follows:
— Ranging back-off,
— Frame structure configuration
— R-amble configuration
2.
RS_Config-CMD (RS Configuration Command) message: A MR-BS either unicasts RS_Config-CMD
message to a RS or multicasts the message to a group of RSs. The message will contain per RS parameters
as follows:
— CID assignments for local CID allocation mode
— Radio environment report threshold for RS group
— Cooperative diversity configuration

mode, where the RS shall follow the pattern instructed by MR-BS to transmit/receive the R-amble. The pattern
is composed by the amble index, and the RS shall transmit/receive the R-amble according to the field where its
amble index is. Start Frame Number is the 8 LSB bits of frame number index used to indicate the starting point
of subsequent R-amble transmission/reception opportunities. In order to coordinate the R-amble
transmission/reception in different MR-cell, a coordinator in backhaul network is needed to ensure the Start
Frame Number parameters sent in different MR-cell will align to the same time. The RS shall start

11.23.5.2 RS autonomously control mode
This field is used for R-amble transmission and monitoring configuration under RS autonomously control mode,
where the RS will autonomously transmit/receive the R-amble without periodic instruction from MR-BS by
defining R-amble repetition patterns and monitoring patterns. The deactivation or activation of the
functionalities of individual RSs can be done by sending (unicast) this message during initial entry of an RS. In
the case of conflict, broadcast message parameters shall supersede the unicast message parameters except for the
case of the parameter M which shall be set only by the unicast message. The detail design of the associated
parameters is stated in 8.4.6.1.1.4. When the RS is instructed to transmit/receive the R-amble transmission
autonomously, the RS shall send the measurements using standard measurement reporting mechanisms already
defined in this document. The RS shall start transmitting/receiving the R-amble at the designated the frame

RS EIRP
The MR-BS shall indicate to the RS the EIRP the RS can utilize on the access DL preamble and advertised in any
DCD message transmitted by the RS on the access link. The EIRP parameter is reported in dBm and quantized in
1dB steps ranging from [TBA]dBm (encoded 0x00) to [TBA]dBm (encoded 0xFF). Values outside this range shall
be assigned the closest extreme.
RS Frame Offset
RS frame offset indicates the offset value between frame number used by the RS’s superordinate station and frame
number that should be used by the RS for whom this message is addressed. When the RS transmits the frame
number in its frame, RS shall keep the offset relative to the frame number used by the superordinate station as
indicated by this value. The value represents LSB 8 bits, unsigned integer for the frame offset.

Relay data early arrival report threshold
When MBS data synchronization with target transmission time is supported, this field defines the threshold used by
RS to determine when to send Access Link Transmission Status feedback header when one or more MAC PDUs
arrives at the RS too early. When the threshold is included, the RS shall send Access Link Transmission Status
feedback header to MR-BS when one or more MAC PDU arrives at the RS earlier than the threshold to the target
transmission time. When this field is set to 0 or not present, RS shall disable the early arrival reporting.

Indicates which antenna the corresponding RS should play the role of. For example, if this field (Bit#0-#3) is a

antennas and this field (Bit#0-#3) is 0b1100, two antennas of the RS shall take the roles of Antenna #0 and #1.
Each antenna will transmit pilots based on the permutation number of antennas as indicated in STC_DL_Zone_IE
and antanna assignment. The MR-BS shall indicate the effective number of antennas being used for cooperative
relaying.
